ATTACIIMENT FOB KARM-IMLACHIITS.

To all whom ift-may concern:

lexact description o the invention, such as will enable others skilled in the art to which it appertains to make anduse thesame.

l This invention relates to new and useful "improvements in attachments vfor farm ma.- 4chinesand the Vprincipal object of the invention is Ito provide a-delviee:which1 is capable of being attached to cultivators, mowmg'inachines and other implements used on ",nothe' object of the 'T without the necessityv ot usinghrses or other .andgahout a 4farm. i

A. furtherfobjec of thegnvention is to provide a device wliicli'inayfibeii'e'a' il mounted on the tongue of the machine, wlnc tongue mfay'besupported oncasters or in an;r other suitable nianner'atits forward end. `A further' object of the invention is to provide power transmitting means for farm machines wherein the sprocket wheels have. their hubs disposed inthe vertical plane of the traction :wheels andconnected to the same by sprocket chains which permitthe traction wheels to yield to forward and rear thrusts due to inequalities of the ground.

lVith these and other 'objet-ls in view; the invention consists in the novel combination and arrangement of parts which will be fully set forth in the followingr specification and accompanying drawings, in which Figure 1 is a side view in elevation of a cllltivator, having this attachmentl applied thereto;

Fig. 2 is a top plan view of Fig. 11;l Fig. l3 is a transverse sectional view on line 3-3 of Fig. 1, illustrating in detail the friction driving gears'and -t Fig. 4 is a longitudinal sectional view through. the friction driving gear illustrating in detail the means for transmitting power to the driving wheels of the device.

dles on which the 'wheels 4: are rotatably mounted. The power frame is designated by the numeral 5 and supports the usual cultivating plows 6 and this' frame is' adjustf able by means of the usual lever'and'segnient 7. Extendin forwardly from the forward 4end of the rame 2, is the tongue 8 on which 4the attachment is mounted and to which the draft animals are usually hitched.

Mounted on the tongue intermediate its ends is a suitable driving motor 9 the drive shaft 10 ofwhich is provided with albeit wheel or ulley 11 over which a driving belt 12 runs. ounted on the tongue in the rear of th'e motor is a suitable bear' 15 'supporting n. transverse shaft 14 provided with i friction disks 16.' One end of the shaft prdthereto a pulley 17 overwhich the belt 12 runs and it wi lthusbeseen that when the motor 9 iset in operation, the pulley will .drive the 'l isks 16. -l 'J Pivotally connected as at 18, to the central pedestal 15 is a link 19, the upper end -of which is `formed with a bearin to receive the forward end of a movables aft 20, the rear end ofwhich is mounted in a suitable bearing :'1 which is positioned sogas because the pinions 22 to constantly engage a beveled gear 23 which is mounted on the intermediate ,shaft :24. The forward end of the shaft 2O has keyed thereto a 4friction wheel 2.1 whiehfs )rovided with a friction face`26 formed of lier, paper or the like,. which friction is of less diameter than the distance between the friction diskslti so that the same will only engage one of said disks at a time. A suitable shifting lever 27 is connected to the friction wheel 25 and provides a means by which the wheel-may be shifted to engage either of the disks. The Jshaft '24 is journaled in suitable bearings 28 -carried onitli'e tongue and projects toward opposite sides of'tlie' fai-mim,r implement on which the device is used. and this'shaft'lias which the driving chains Pass. These driving chains pass around the wheels 4 as clearly shown in Fig. 1 and provide a means for propelling the implement over the ground which is being worked.

It will he apparent from the foregoing, that in use the motor 9 is set in operation thus drivin the Juliey 17 and the friction disks 16. l pon shifting the shaftQO in one or the other direction 1t will be seen that the friction wheel 25 will engags one or the other of. the friction disks there y transmitting power hrough the pinion 22 and gear 23 to the shaft 24 which, in turnV drives the main drive sha'ft 31 by means of the belt 33 and thereby causes the sprockets 34 to revolve and rotate the wheels 4. It will he evident that the chain will when-passing underV the wheels 4 form a tread which will facilitate the driving of the device over the ground and it will be evident that the power of a driving mechanism constructed in accoi-dance with this invention will be increased to the,maximum. l

As illustrated in Fig. 1 the wheels 4 have their hubs disposed in the vertical plane of the sprocket wheels 34 ivhereby the wheels are free to yield 'to forward and rear thrust during trave lVhile in the foregoing there has been shown and described the preferred cmbodi.-

ment of this invention, it is to be understood that such changes may befmade in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims. l

What is claimed isz- 1. A ground working apparatus including a tongue, a motor arranged on the tongue, a driven shaft connected with the 40 shaft of the motor and extending parallel thereto, a pair of spaced friction disks mounted on said driven shaft, a friction wheel disposed between said disks, means to enga said t lsks, a drive shaft connected with said` i, friction wheel, sprockets on said drive shaft, and chains extending aboutsaid sprockets and the periphery of the wheel of the apparatus.

2. A ground working apparatus including a tongue, a motor arranged on the tongue, frlctional gearing connected with the motor, a. transverse drive shaft connected withsaid frictional gearing, sprockets for said drive shaft, wheels suspended below said drive shaft, and drive chains extending about said wheels and said sprockets, said Wheels having their hubs disposed in the vertical plane of said sprockets whereby the wheels may yield to the forward and rear thrust during travel.

3. A ground working apparatus including a mot-or arranged on the tongue, a transverse drive shaft connected with said motor, wheels suspended below said drive shaft, sprockets for said drive shaft, and drii'e chains extendin about said wheels and said sprockets, sait wheels having their hubs in the vertical plane of said sprockets whereby the wheels 'may yield to the forv'vard and rear thrust during travel.

In testimony whereof I ailix my signature in'prese-nce of two witnesses.
